Background Decreased leg muscle strength is a major determinant of reduced function in patients with knee osteoarthritis (OA). The identification of a strength parameter that is best correlated with functional performance is important for monitoring rehabilitation results. Objective To determine which muscle strength measurements show the highest correlation with functional capacity in patients with severe knee OA shortly before total knee arthroplasty (TKA). Design Cross‐sectional exploratory study. Setting Outpatient rehabilitation department at a university teaching hospital. Patients The sample included 75 patients (51 female) scheduled for primary TKA, recruited through multistage sampling. Methods or Interventions Independent variables were peak isometric, isokinetic concentric, and eccentric leg extensor strength measured on the leg press, as well as peak isometric knee extensor strength measured on the strength chair. Two multiple regression analyses were performed, one including all strength measures and the other including all of the strength ratios. Pearson correlation coefficients were calculated between the strength measures and functional test scores. Main Outcome Measurements Dependent variables were the Timed Up and Go Test (TUG) and the Stair Test (ST). Results The regression analysis including all strength measures could explain 11.9% of the variance of the TUG (P = .068, not significant [NS]) and 21.5% of the variance of the ST (P = .009, significant). The regression model for the strength ratios explained 11.8% of the variance of the TUG (P = .090, NS) and 6.3% of the ST (P = .217, NS). Conclusions Although univariate analysis confirmed significant correlations between strength measurements and functional tests, multiple regression analysis revealed a higher predictive value for the ST than for the TUG. The use of both muscle strength tests and performance‐based function tests is advisable to evaluate functional impairments of patients with knee OA. Level of Evidence III

“…In recent years, vibratory therapies have emerged as potential helping aids to rehabilitation processes. These have demonstrated improvements in patients with multiple sclerosis, in recovery of muscle strength and function, in preventing bone loss and even in accelerating the healing of the bone without inhibiting the healing of the ligament in traumatic lesions [13][14][15][16][17]. Other authors have shown that the induction of vibration to the wrist can aid in the rehabilitation process after the occurrence of a traumatic injury.…”

Wrist injuries are a very common type of pathology that can compromise most daily tasks. Conventional therapy is dependent on the availability of physiotherapists as well as devices designed for this purpose. Conventional devices do not accompany the patient throughout their rehabilitation process, requiring their constant replacement. Vibratory therapies emerged in recent years and have demonstrated several benefits in this area. However, there are few vibratory devices designed for wrist rehabilitation. In this paper, we propose two different portable and active models for wrist rehabilitation based on vibratory therapy for wrist rehabilitation. The first model has a cylindrical shape and the second model has a dumbbell shape. The results obtained showed that vibratory therapy can assist the wrist rehabilitation because it promoted improvements in joint amplitude gain in all wrist movements. Furthermore, the second device demonstrated higher joint gains than the first device. In addition, the results obtained from the measurement of accelerations demonstrate that the natural frequencies of both devices are adequate for wrist and forearm rehabilitation as well as the mode of vibration. There are differences between what the simulations predicted and what was obtained in practice in terms of natural frequency values.

Knee osteoarthritis is associated with deficits in muscle strength, muscle mass, and physical functioning. These muscle‐related deficits are acutely exacerbated following total knee arthroplasty (TKA) and persist long after surgery, despite the application of standardized rehabilitation programs that include physical/functional training. Resistance exercise training (RET) has been shown to be a highly effective strategy to improve muscle‐related outcomes in healthy as well as clinical populations. However, the use of RET in traditional rehabilitation programs after TKA is limited. In this narrative review, we provide an updated view on whether adding RET to the standard rehabilitation (SR) in the recovery period (up to 1 year) after TKA leads to greater improvements in muscle‐related outcomes when compared to SR alone. Overall, research findings clearly indicate that both muscle strength and muscle mass can be improved to a greater extent with RET‐based rehabilitation compared to SR. Additionally, measures of physical functioning that rely on quadriceps strength and balance (e.g., stair climbing, chair standing, etc.) also appear to benefit more from a RET‐based program compared to SR, especially in patients with low levels of physical functioning. Importantly though, for RET to be optimally effective, it should be performed at 70%–80% of the one‐repetition maximum, with 3–4 sets per exercise, with a minimum of 3 times per week for 8 weeks. Based upon this narrative review, we recommend that such high‐intensity progressive RET should be incorporated into standard programs during rehabilitation after TKA.
